What is CVE-2026-85425?

The MOOS-IvP iSay application, up to version 24.8.1, contains a vulnerability that allows an attacker to perform remote code execution via the SAY_MOOS variable handler. This handler is susceptible to accepting unsanitized text, enabling attackers to inject backticks or command substitution syntax into SAY_MOOS messages. As a result, malicious users can execute arbitrary commands within the context of the iSay process, potentially compromising system integrity and confidentiality.
